It really shows Eddie has been working with power. He recognized the problem and the fix straight away!

Awesome! Keep on testing!

Great job Eddie 👌...
-
This was wonderful, I've waited patiently for this over the last few months and it was well worth the wait! Thank you, I'll perform the modification. This will help in my beginner electronic endeavors. I'll keep an eye out for future mods and vids. Love watching your stuff... sincerely a beginner electronic enthusiast ;)

Hi Eddie, thank you sooo much for another Amazing Video and Great Tutoring.
-
Really enjoyed the detail in what you were doing. I'm not quite ready (experience wise) to do this to my Kaiweets, but I plan to refer back to this video when I am. I followed along scoping my ps and learned some things. Thanks!
-
I gonna get one and do the same modification. You are the master, thank you!
-
Good video, i like ! I think we need to send some funds to help you get a bigger bench & stronger :) Good work Eddie !
-
Now you're talking! Nice job with the noise, but I'll like to see the second video improving it even more! Thanks again for your ideos!
-
Thanks for great video. I've got this one and had to get more amps one that could drive DC motors that require 22 amps to start.

Very KNOWLEDGEABLE Thanks 👍 Kiss Anulog From Nick Ayivor from London England UK 🇬🇧

thanks for video sir

I wish I understood this video better, but I guess that's what learning is all about 😅 I'm subscribing!

I just got one on Amazon prime for $76 plus tax. Great deal, thx for the videos.
-
It would be great to see a side by side comparison of several budget switching power supplies to see what is best out of the box.

Back in high school, I think I attempted this kinda mod on every bench supply I owned. They were all linear, most of them were boat anchors and way less (HF) noisy than comparable supplies today...you know, mostly just 60/120Hz ripple artifacts sneaking through and visible when the scope was zoomed way into the noise floor. For whatever reason, I thought the outputs all needed to be cleaned up. I think I only managed to make them worse. "Uhhh. What's a common-mode? The coil goes after the cap, right? Uhhhh" I need to open one up someday and see exactly what I did. Surely it'll be worthy of a spot in the marvelous museum of kludgy blunders.

Hi Eddie ! A fantastic video!!! THANK YOU for taking the time to present and edit this well planned and executed video. I just bought one of these KAIWEETS power supplies (based on your earlier review video) and am interested in doing these mods to mine soon as well. You identify all the cap. values you used nicely,,, BUT I believe you missed (around 14:09 in the video) the value of the blue square shaped polypropylene capacitor you inserted just before the inductor. As I don't have many capacitors around, I will be buying some for this project - so I would be very grateful if you could reply and let me know. I have re-watched your video a few times and I have tried reading as many of the other comments hoping to see if this was already addressed,,, if it was, I apologize, I must have missed it. THANKS AGAIN... (and keeping my fingers crossed that you see this comment so many moons past your original posting).

You got my attention...
-
Thanks Eddie. To me it looks like they got the snubbers wrong. The other thing I'd like to see is how the noise looks under load conditions. I see you like the Instek scope. I just picked up their electronic load, not cheap but really nice.

brilliant..
